Citizens United president David Bossie added that he’s thrilled Walker will join the already impressive lineup of speakers.

“Congressman Steve King and I are thrilled Governor Scott Walker, a leading conservative voice, plans to attend the Iowa Freedom Summit,” Bossie said. “The Iowa Caucus is the first step for any conservative running for the Republican nomination and we are pleased Governor Walker appreciates and respects its importance.”

Walker, a potential 2016 Republican presidential candidate, has held off the left for years amid numerous attempts by Democrats to take him down. During his tenure as governor, he’s cut unemployment in Wisconsin substantially—it was 7.8 percent when he took office and it’s currently down to 5.2 percent. He cut taxes by $2 billion, including lowering property taxes in the state compared to their rise of 27 percent in Wisconsin in the decade before he took office. Taxpayers have saved an estimated $3 billion at the state and local level, too, thanks to Walker’s collective bargaining reforms—the catalyst which caused the institutional left, organized labor, and democrats to target him. He also froze tuition for all University of Wisconsin system students for two years and is aiming to do so again for another two years because of the system’s surplus.

The Iowa Freedom Summit event takes place on Saturday Jan. 24, 2015 at Hoyt Sherman Place in Des Moines. “The Freedom Summit will focus on how we can get America back on track by focusing on our core conservative principles of pro-growth economics, social conservatism, and a strong national defense,” the event’s website states.
